Offering accurate, clear, and articulate voice intelligibility and massive SPL capabilities, the 4266 Omnidirectional Headset Microphone allows users to sing or speak into the mic without the concern of distortion. This headset sits snug and securely around the head, making it the perfect choice for active performers who don't want to feel the presence of the microphone. The adjustable microphone can fit any head size or head shape, while mounting securely and remaining discrete. Simply rotate the boom and ear hook to use the microphone on whichever side you prefer, and the connector separates the microphone from the cable, allowing you to swap broken cables or connectors quickly and easily. CORE by DPA - The powerful new technology at the center of DPA's miniature microphones, CORE minimizes distortion. Whether whispering or screaming, you'll notice the articulation, openness, and clarity. CORE allows you to squeeze a more performance out of your mics, giving the 4266 an extra 14dB in dynamic range, due to the THD point being 1% higher. IP58 certified All CORE by DPA technology microphones are IP58 certified. The ruggedness and durability is achieved through a range of technologies: Water-repellant nano-coating of the cover and housing Hermetic sealing of the sensitive amplifier at the core of the mic Dual gold plating of the diaphragm A bit about omnis - Omnidirectional microphones are sensitive at all angles, and basically pick up sound equally from all directions. This results in a very natural and realistic sound compared to cardioid mics. Not only are omni mics commonly used to pick up ambient noise, but also for miking big sound sources like choirs in recording situations. One drawback of omnis using this polar pattern is the amount of feedback they can sometimes produce in a live scenario. That's where DPA omni mics come in. When used close to the signal source, the balanced frequency response makes these mics a versatile addition to your audio toolkit. They often deliver a more natural sound, can handle very high SPLs, are immune to proximity effect, and are not as sensitive to wind, pop, or handling noise. Adapter system gives you flexibility - Wireless system adapters offer versatile, easy, and cost-effective possibilities. No longer tied to a single wireless system, as your situation changes, you can simply change adapters instead of incurring the expense of buying an entirely new mic - and when you do switch, there is no loss or change in signal quality. The DPA series of miniature microphones are compatible with all major wireless microphone systems from Lectrosonics, Sennheiser, Shure, Sony, Zaxcom and more. DPA Microphones' innovative adapter system is unique in the industry - protecting your investment in high fidelity for years to come.
